“不改变文物原状”作为中国文物建筑保护的最基本原则被写入《中华人民共和国文物保护法》中。但对这一原则的内涵及“原状”等问题的理解，却长期以来一直是中国文物建筑保护领域讨论的焦点。论文以我国不同时期对“不改变文物原状”的表述为切入点，结合同期具有代表性的文物保护修缮工程实例，在梳理中国文物建筑保护历程的基础上，对保护原则和保护理念的演变进行了探讨。论文按照时间顺序把中国文物建筑保护历程分为四个阶段，在不同阶段分别选取了正定隆兴寺转轮藏殿、赵县安济桥、五台南禅寺、正定隆兴寺摩尼殿、朔州崇福寺弥陀殿、太原晋祠圣母殿和蓟县独乐寺观音阁等保护工程进行案例分析，并结合时代背景、法规政策、保护工作的阐述和对保护方案制定过程及修缮后效果、影响的分析，对“保存或恢复原状”、“恢复原状或者保存现状”、“整旧如旧”、“不改变文物原状”这些不同阶段文物建筑保护原则不同表述的内涵进行探讨，指出中国文物建筑保护理念从以“恢复原状”为主要目标，到逐步对历史价值、历史信息进行关注的发展过程。论文最后在总结回顾的基础上，对我国不同阶段文物建筑保护理念发生变化的原因进行了分析，提出：中国文物建筑保护理念从20世纪50年代学习苏联模式到20世纪80年代改革开放，始终受社会发展背景和主流价值观的重要影响；对文物建筑保护工程实践的经验总结也促使了保护界对保护理念和原则的进一步探讨。论文共分6章。第1章：综合介绍论文的研究背景、选题意义和国内外的研究状况，对相关概念进行解释，对案例选择、研究时限和范围进行了说明，归纳总结了论文的研究内容和研究方法。第2章：对1949年之前中国文物建筑保护和研究情况进行整理，分析了我国文物建筑保护理念在形成之初的特点。第3章：概述了1949——1965年这一时期中国文物建筑保护工作的开展情况，并结合国内时代背景、苏联影响、法规政策制定以及保护工程实践的阐述，对这一阶段的文物建筑保护理念，特别是“恢复原状或者保持现状”的文物建筑保护原则进行了分析和探讨。第4章：以五台南禅寺修缮为例，阐述了全面“恢复原状”的实践探索。第5章：梳理了20世纪80年代以后中国文物建筑保护工作的情况，“不改变文物原状”的提出以及保护理念的演变和发展。文物建筑的“历史价值和历史信息”逐渐引起保护界的更多关注。第6章：总结。
“Retaining Historic Condition”, as the essential principle, has been recorded inLaw of the Peoples Republic of China on the Protection of Cultural Relics. However, the comprehension of its connotation as well as of what is “historic condition” has been remaining the hot topic when discussing architecturalconservation of cultural relics in China. Using the contemporaneously representative projects on conserving and maintaining cultural relics as examples, this paper discusses the evolvement of conserving conceptions and its principles according to different expressions about “Retaining Historic Condition” in different times, with bases on the history of architectural conservation on cultural relics in China.In terms of time, the paper divides the course of architectural conservation on cultural relics in China into four phases, and chooses such representative conserving projects to analyze their details as the Library Building of Long-Xing Temple; the An-ji Bridge in Zhaozhou; the main hall of Nan-Chan Temple; the Mo-ni Hall of Long-Xing Temple; the Mi-tuo Hall of Chong-Fu Temple, the Sheng-Mu Hall of Jin-ci Temple; theKwan-yin Pavilion of Du-le Temple. Based on era backgrounds, laws and regulations, as well as the summary of conservation work and the analysis on the process of making conservation plans and on its effect and influence after maintaining, the paper illustrates the development of conserving conception on the architecture of cultural relics in China, from focusing the main target of “restore historic condition” to moving to pay attention to its historic value and information by probing into the connotations of different expressions about the conserving principles in different phases, such as “to conserve or restore historic condition”, “to restore historic condition or conserve existing condition”, “to maintain historic condition as it had been” and “retaining historic condition”.After summarizing and retrospect on such evolvement and development, the paper finally analyzes the reason why principles and theories on conserving the architecture of cultural relics in China has been changing in different times. It points out that the conserving theroy on architecture of cultural relics in China has experienced a distinctive evolvement from 1950s, when studying the former Soviet Union pattern was the mainstream, to 1980s, when the Reforming and Opening began, which has always been influenced by the social backgrounds and mainstream values; meanwhile, the practical experience on architectural conservation of cultural relics has been summed up during this long course, which also has made it possible to discuss its conception and principle further.There are six chapters in this paper. Chapter 1: it generally introduces the study backgrounds, the reason why the author chose this theme and the actual condition in this field abroad as well as in China. It also explains some relative concepts and why the author chose those conserving projects as examples; in addition, this part also concludes its study methods and its content. Chapter 2: by stating the information concerning the architectural conservation and the academic status before new China was founded, it analyzes the characteristics of architectural conservation during its initial stages. Chapter 3: it generally discusses the development of architectural conservation work from 1950 to 1965. Then based on the temporal backgrounds, the influence from former Soviet Union, as well as laws and regulations and the practical work on conservation, this chapter analyzes and discusses the conserving conception on the architecture of cultural relics, especially the “to restore historic condition or conserve actuality” principle. Chapter 4: Setting the conservation work in the main hall of Nan-chan Temple as an example, the chapter illustrates the practical exploration on “to restore historic condition” principle in full scale. Chapter 5: this chapter combs the development of architectural conservation in China, as well as the evolvement of conserving conception after 1980s. According to this part of paper, the conserving conception has evolved from the original two meanings in “retaining historic condition” principle, “to restore historic condition” or “to conserve existing condition”, to the thoughts and concerns on its historic value and information. Chapter 6: conclusion.
